I guess first I'd invest in some Sears plastic socket rails (with the detent ball on them) and start organizing all of them into "sets." 6pt, 12pt, etc.
this will also let you know how many you're missing to form complete sets.
I like to avoid the metal racks with the metal holders like they were hookers with visible cold sores... They always bend, the metal clips always lose their spring tension and the socket falls off, etc.
Every now and then socket trays/boxes (little open box/tray with the handle on top that swings down out of the way) from Mac, Snap-on, etc. show up here in the classifieds too.
The Hansen trays with the posts are popular, but they usually hold standard and deep on the same tray. I like the racks because when I'm working on something I like to take the whole set of 1/2-inch or 3/8-inch sockets to the work piece, as I usually need several different sizes. Your mileage may vary.
Once you have them all laid out and on racks or in storage trays, then you'll know how much space you need for them. At that point you can thin the herd too, and sell some.
I've got a full set of standard and deep well in all three drives in my road trip box, a full craftsman box set in my wife's Corvair, and two sets of each in my main shop box. This many in my shop box lets me have one for me, and one for a buddy or my son if we're wrenching on a project together (work goes MUCH quicker when everyone has their own tools). It also gives me an immediate back-up if one breaks.
Then I set my 16 year old up with a full set.
The rest went to the swap meet.

? I guess I am a hoarder. I'll buy 10mm, 13mm, and 15mm as well as 1/2", 7/16" and 9/16" anytime I see them cheap. My kids loose them, my wife looses them, heck even I have been known to lose one or two now and again.
